TOPEAK M size Black Saddle Bag I'm selling this after using it for a few months because I no longer need it. I'll include an Alien Tail Light with flashing and solid light modes, activated by pressing the "forehead" of the light. (It can be attached directly to the seat post or to the saddle bag.) It has a zipper to adjust the capacity, which I think is very useful. Please note that the zipper pull for adjusting the capacity is missing, as shown in the photos. To save on shipping costs, I will compress the bag for shipping.
